Departing DS9

In-Universe:
The U.S.S. Defiant makes a steady turn to port with DS9 in the background and then jumps to warp.

Production:
Not sure if the Defiant that is flying in front of the station was CG, but I'm guessing it's the Studio model. The Defiant was created in CGI by VisionArt as well as the warp effect. - Daniel Kramer
